What symbols are used on the TCAS page to represent TCAS supplemental information?

The symbols used on the TCAS (Traffic Collision Avoidance System) page to represent TCAS supplemental information are specifically designed to convey critical altitude and vertical speed data to the pilot. The up arrow signifies an aircraft that is climbing, while the down arrow indicates an aircraft that is descending. The plus sign is used to display a proactive increase in altitude, enhancing situational awareness for the crew. This set of symbols allows pilots to quickly understand the movements and intentions of nearby traffic, facilitating timely and effective decision-making to avoid potential collisions.

The use of these specific symbols is tailored for clarity and rapid interpretation, which is essential in high-stress situations, such as managing airspace with multiple aircraft. Their design enhances the overall effectiveness of the TCAS by providing intuitive visual cues that are easily distinguished by pilots during flight operations.
